Edge - Rim Light

Create a quick 2D Rim Light in Nuke

Using Matrix 3x3

This tutorial can be helpful if you want to create a really fast Rim Light in 2D. Just need the matte of the character/object you want and move the rotate slider. First of all I would like to thank Sabine Janetzka for introducing me to this technique with the Matrices.

You can download the Gizmo for Nuke here:

Overview

In Nuke bring a Matrix Node from here: Filter → Matrix... and select the dimension of the matrix. In this case 3x3.

Edge, Rim light, matrix, nuke, matrices, 3x3

Convolution Matrix, matrix, nuke, matrices, 3x3

When you will find this Textfield, you can copy-paste the values directly in another Matrix 3x3 node in Nuke.

This is our original image: a simple circle 2D. You can get it with the Radial Node in Nuke.



This GIF is showing you the result of this Gizmo: starting from a sphere we will get the Rim Light!
